Mac,
This is solid advice. The fancy, shamnsy, "high end" trinket pedelers would prefer you buy their $100+ connectors. You however left out the final 2 steps. (Guess you figured folks would figure out for themselves) For those who didn't, once you have smashed the wire flat you will need to trim the newly flattened wire to the proper width. Use a good sharp pair of wire cutters for this. Lastly, use a dab of super glue to attach to your connector. Solder is a hassle, and makes that carcinogenic smoke.
